Comparison of the smoking habits of 32 adult male Africans with carcinoma of the bronchus and 32 controls showed that 87.5% of the patients with lung cancer were cigarette smokers compared with only 22% of the controls. The distribution of histological types of growth confirmed findings by other workers.The absence of atmospheric pollution in Rhodesia makes it likely that cigarette-smoking is the most important causative factor in the aetiology of lung cancer among Rhodesian Africans. Further work is needed to determine the level of consumption of cigarettes and type of smoking habits which lead to a serious risk of cancer.
对32名患有支气管癌的成年非洲男性和32名对照者的吸烟习惯进行比较，结果显示，87.5%的肺癌患者吸烟，而对照者中只有22%吸烟。生长组织学类型的分布证实了其他研究人员的发现。罗德西亚没有大气污染，这使得吸烟很可能是罗德西亚非洲人肺癌病因中最重要的致病因素。需要进一步开展工作，以确定导致严重癌症风险的香烟消费水平和吸烟习惯类型。
